CHURN.

Specification of Letters Patent.

Patented March 2, 1909.

Application filed October 8, 1908. Serial No. 156,790.

To all whom it may concern:

Be it known that I, CARL S. MCCALMAN, a citizen of the United States, residing at Mapleton, county of Monona, and State of Iowa, have invented certain new and useful Improvements in Churns, of which the fol lowing is a specification.

My invention relates to improvements in that class of churns which comprise a stationary receptacle provided with a hinged cover in which is rotatably mounted a vertical dasher shaft.

The object of my invention is to provide improved means for driving the dasher shaft whereby the hinged cover will not be subjected to the weight of the operating machinery which would otherwise cause difficulty in raising the cover and would also cause the hinges of the cover to wear rapidly and become loose.

A further object of my invention is to provide an improved arrangement of the operating mechanism whereby the balance-wheel and other parts may be located in convenient and advantageous positions.

My invention will be more readily understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a side elevation of one form of my improved device, Fig. 2 is a plan view thereof, Fig. 3 is a fragmentary side elevation showing the cover in raised position, Fig. 4 is a vertical section on the line of Fig. '2, Fig. 5 is a plan view of a modified form of my device, Fig. 6 is a fragmentary sectional view on the line y-y of Fig. 5, Fig. 7 is a side elevation of the device shown in Fig. 5, and Fig. 8 is an end elevation thereof.

In the views referring to the construction shown in Figs. 1 to 4 inclusive, 1 is the base on which is mounted the rectangular receptacle 2 adapted to receive the cream. dasher shaft provided with dashers 4 and rotatably mounted in bearings 5 and 6 secured to the inside of the receptacle. 7 is a bevel gear mounted in a bearing 8 secured to a cover mounted on hinges 10 adapted to close the receptacle. The bevel gear has a rectangular socket 11 adapted to be brought into engagement with the squared upper end 12 of the dasher by the closing of the cover 9. 13 is a latch adapted to hold the cover in closed position. 14 is a shaft comprising two sections 15 and 16 pivoted together as at 17. The section 15 is mounted in a fixed Sisa bearing 18 secured to the receptacle and has a bevel gear 19 fixed thereon. The section 16 is mounted in a bearing 20 secured to the cover and has a bevel pinion 21 fixed thereon which engages the bevel gear 7. 22 is a vertical shaft mounted in bearings 23 secured to the side of the receptacle. This shaft has bevel pinions 24 and 25 fixed thereon the pinion 24 engaging the gear 19. 26 is a horizontal shaft mounted in bearings 27 secured to the receptacle. This shaft has a belt pulley 28, a balance-wheel 29 and a bevel gear 30 fixed thereon, the bevel gear 30 engaging the pinion 25.

The operation of the device is apparent from the drawings.

The dasher shaft 3 is driven from the belt pulley 28 through the medium of the shafts 26, 22 and 14 and the train of gears 30, 25, 2 1, 19, 21 and 7.

It will be noted that the pivoted points of the hinges 10 and the shaft 14 lie in a straight line this construction permitting the cover to be raised as shown in Fig. 3.

Having described my invention what I claim as new, and desire to secure by Letters Patent, is:-

1. In a churn, a receptacle 0 on at the top, a vertical shaft provided witi dashers rotatably mounted in said receptacle, a pivotally mounted cover adapted to close said receptacle, said member and said shaft having portions adapted to be brought into engagement by the closing of said cover, a bearing secured to said cover, a shaft comprising two sections pivoted together having one section rotatably mounted in said hearing, a fixed bearing in which the other end of the shaft is mounted, a rotatable member fixed to said shaft engaging the first mentioned rotatable member, and means for rotating said shaft, substantially as described.

2. In a churn, a receptacle open at the top, a shaft provided with dashers rotatably mounted in the receptacle, a cover mounted to swing about a horizontal axis adapted to close said receptacle, a bevel gear rotatably mounted on the cover having a socket adapted to be brought into engagement with a portion of the shaft by the closing of the cover, a shaft comprising two sections pivoted together, a fixed horizontal bearing in which one section of said shaft is mounted, a bearing secured to the cover in which the other section of the shaft is mounted, a bevel pinion fined to said shaft engaging said bevel gear, a horizontal shaft mounted on the side of the receptacle, 2, balance-wheel fixed to this shaft, means for rotating said shaft, and connections between the two last mentioned 5 shafts whereby the rotatlon of one Wlll cause the other to rotate, substantially as described.

In testimony whereof I have signed my I nanie to this specification in the presence of two subscribing witnesses.
